Glass cookware is an amorphous non-metallic material, which is generally made of a variety of inorganic minerals as the main raw material, and a small amount of auxiliary raw materials are added.

It is widely used in buildings to separate wind and transmit light. It is a mixture. There are also colored glass that is mixed with certain metal oxides or salts to show color, and tempered glass made by physical or chemical methods. Sometimes some transparent plastics are also called glass

In terms of production process: Ordinary flat glass is a transparent and colorless flat glass that is prepared by mixing raw materials in proportions, melting at high temperature in a furnace, and producing transparent and colorless flat glass by vertical drawing method, flat drawing method, and rolling method.

Float glass is prepared by proportioning the raw materials and melted at a high temperature in the melting furnace. The molten glass flows continuously from the kiln and floats on the molten metal surface, spreading out into a uniformly thick, polished glass ribbon, which will be separated from the molten metal after cooling and hardening. It is a transparent colorless flat glass that is cut after annealing.
